fo all whom may concern:

Be it known that I, TML D. GRAY. of Milwaukee, in the county otl Milwaukee and State of Wrisconsin, have invented certain Improvements in Centrifugal Reels, of which the fol- -removing from the body, before it Aenters the `end view ofthe tail end ofthe reel.

reel, dough-balls and other coarse foreign matters, to means for directing the body toward the bolting-surface and maintaining it in proximity thereto, and to peculiar driving mechanism hereinafter described in detail.

Referring to the accompanying drawings, Figure l represents a longitudinal section through a machine containing my improve ments, the lower half of the reel and beaters being represented in section, while the upper half is shown in a side elevation. Fig. 2 is a vertical cross-section of the reel, one side being taken on the line m x and the other side on the line y y of Fig. 1. Fig. 3 represents an Fig. 4 is an end elevation of the head of the reel, the

outer end of the body or casing being removedv to expose the interior parts. Fig. 5 is a vertical cross-section through the head of the Fig. 6 is a longitudinal section ofthe machine through the center, showing the detlecting-cone and cylinder therein. Figs. 7 and 8 are elevations of the head ofthe machine, showing the driving-chain in its two positions.

Referring to the drawings, A represents a rectangular frame,adapted to support the operating parts, and suitably closed or incased to form a body or chamber.

B represents the main shaft,passed horizon tally through the upper portion of the body,

and provided with radial arms or equivalent supports, C, bearing at their outer ends the longitudinal blades or beaters D, which are ordinarily of a slightly-curved or spiral form.

E represents a horizontal cylinder or reel,

covered with bolting-cloth or equivalent pervious material, and arranged to encircle the series of beaters, as shown. This reel is encircled at or near its ends by iianges, which will be sustained and driven by means of pul leys F,bearing thereunder, las shownin Fig. 4, the pulleys at one end being ordinarily provided with gear-t-eeth engaging corresponding teeth on the tianges, for the purpose of imparting a positive motion to the reel. The pulleys under one or both sides of the reel are mounted upon a longitudinal shaft, G, which is projected at one end ot' the frame, and provided with a drivingpulley, H, as shown in Fig. 7.

As regards the construction and arrangeballs I mount within the head of the reel a perforated conical basket or screen, J, into which the material is delivered by the feedspout, and through which the material is com- This pelled to pass in order to enter the reel. basket is arranged, as shown, centrally around the beater-shaft, being secured cit-her to said shaft or to the head of the reel, so as to receive a rotary motion therefrom. The basket or screen is arranged with its larger end outward. Being thus arranged the free and iine material will pass readily through its Vmeshes or openings, which are quite coarse, into the recl,while the dough-balls and coarse impurities too large to pass through the cone roll down the inclined surface, and are discharged, as indicated by the arrows, outside of the reel.

Being thus discharged, the dough-balls descend into the usual passage, K, at the end of the machine. In this passage I locate, as

This sheet is ICO joined at its lower edge to the side of the machine, so that the dough-balls lodging thereon will be retained, While the finer material will pass through into the speck-box or receptacle below, from which they are commonly spouted to the elevator that feeds the reel.

For the purpose of permitting the convenient removal of the dough-balls, a dischargeopening is made in the side of the machine,op posite the lower end of the screen L, and closed by means of a door, M, through which the balls may be discharged.

Hitherto it has been customary to construct the reels for the present class of machines with open ends, having large openings therein through which the air could freely circulate. In order to avoid the difficulties incident to such construction, I close both ends of the reel by the tight heads or plates inserted therein, as shown at N and O in the drawings. The plate or head N at the head of the reel is perforated only to receive the cone J, through which the material is introduced, while the *plate O at the tail of the reel is completely closed, except at the periphery,where it is provided, as shown in Fig. 3, with small openings Q, through which the coarse material or tailings may escape.- In practice it is found that by practically closing the two ends of the reel its action is improved, and the capacity of the machine greatly increased.

Referring next to the deflectors for causing the meal and air to be thrown outward, subject to the action of the beaters and the boltingsurface, reference is to be had particularly to Figs. l and 6, wherein it will be perceived 4that sheet-metal cones A* are mounted centrally around the beater-shaft with their faces toward the tail of the reel. .The cones may vary in diameter at the base; but itis preferred, as shown in the drawings, to extend them outward to the inner edge of the blades or beaters-or, in other words, to a point but a few inches from the inner surface of the bolting-cloth. f

In Fig. l I have represented a single cone arranged at the head of the machine, with a cylinder, Bt, jointed to its base and extending thence to the tail end of the reel. f

In Fig. 6 I have represented three cones arranged at different points in the length of the reel, the material and the air-currents being directedloutward by the several cones in succession, an inward or central movement of the material being permitted, however, between each cone and the next. The cone nearest the tail is connected withacylinder, forming a rearward-extension thereof.

Referring next to the means for imparting the rotary motion to thevreel and the beatershaft, attention is directed particularly to Figs. 6 and 7. The beater-shaft B, and the shaft of the upper conveyer, mounted in the base of the machine, as usual, areY provided, respectively, with sprocket-wheels T and U. A driving-chain engages with the sprocketwheels T and U, and also with the sprocketwheel of thepulley H, through whichmotion is communicated to the reel, as before described. The chain V is acted upon and subjected to the proper degree of tension by means of an idle-pulley, W, sustained by a journal on a slotted adjustable plate secured to the main frame by bolts X. The position of the idler W may be varied in such manner as to admit ofthe driving-chain being passed over the inside of the lfree driving-pulley H, as shown in Fig. 6, or over the outside of said pulley, as shown in Fig. 7.v The idler will serve in either case to keep the chain in the required position, and to maintain the proper tension of the` same. When the chain is applied as shown in Fig. 5, the reel or bolt will be caused to revolve in the same diree.

tion as the beaters, but, owing to the relative size of the driving-wheels, at a slower rate of speed. When, however, the driving-chain is applied as in Fig. 6, the reel will be revolved in the opposite direction from that in which the beaters are turned.A This adaptability of the machine for a reversal of the motion of lthe cylinder is advantageous in that it permits the motion to be adapted for the successful treatment of different kinds of material, and of material under different conditions. While it is preferred to employ the sprocket chains and pulleys, it is obvious that smooth or grooved pulleys and belts may be substiv tuted. As regards the reversible chain B, it

is obvious that it may be passed around a guiding-pulley other than that which is used to drive the conveyers, if desired.A It is also YOO obvious that the chain may be employed in IIO material from the exterior surface of the reel.

or bolt, I provide a rotary brush extending lengthwise beneath the bolt, as represented in Fig. 2. This brush, which may be constructed in any suitable manner, has its shaft mounted in bearings at the ends ofthe main frame, and is driven by means of a pinion, Y, secured to one end of said shaft and engaging with a gear-wheel, Z, applied to the shaft It' of the upper conveyer. This gear wheel Z also serves the purpose of communicating motion to a second gear, Z', secured to the shaft of the lower conveyer.

The two conveyers are constructed and mounted one above the other in the base of the 'machine, and separated from each other by return or division boards in the ordinary manner, to permit the separation of the material matters and things which are hereinafter claimed, and as to all matters which may be described or shown, but which are not claimed, the right is reserved to make the same the subject of a separate application.

I do not claim herein a single cone located in the interior of the reel to direct the material toward the bolting-surface, being aware that a cone for this purpose has been located in the tail end of a reel.

Having thus described my invention, what I claim is- 1. The combination ofthe revolving bolt or cylinder, the revolving conical screen, a receptacle for the coarse matters discharged from said screen, and a secondary screen located in said receptacle, whereby the coarse and fine materials delivered from the conical screen are separated from each other.

2. In combination with the body or casing havingthe chamber at its head, the revolving bolt or cylinder, the conical screen, the inclined screen havinga space or chamber thereunder, and the door or outlet above said inclined screen. j

3. In combination with the horizontal reel and the rotaryr beaters therein, one or more centrallyarranged cones Within the reel and beaters, and a cylinder or cylinders joined to the bases of the cones, as shown.

4. ln combination with the beater-shaft and its pulley, the rcel-driving shaft and its pulley, the adjustable idler, and the endless driving-chain passing around said pulleys, substantially as described.

5. The combination, with the beater-shaft and its pulley, of the reeldriving shaft and its pulley, the adjustable idler, the pulley upon the conveyer-shaft, and the endless chain acting upon said pulleys, substantially as described.

6. In combination with the beater-shaft and its pulley, the reel-driving shaft and its pulley, the idler, and the driving-chain acting upon the three pulleys and reversible, as described, whereby the motion of the reel with respect to the beaters may be reversed at will.
